Electors would not be cast for a unqualified candidate or accepted by the EC.
The constitution refers to a “majority of the electoral votes appointed...” and they are appointed by the States. So the decision first rests with the States. These are sent to the President of the Senate who opens them in front of the whole Congress. Now I would not assume that should Zero be disqualified that would mean the states would all just give them to Biden. Should they do so that opens up a whole can of worms wrt how to select a VP.
Electors are not “Democrat” or “Republican” they are completely free agents. How they would react to such a constitutional crisis as this would be is totally unpredictable.
I do agree this would end in the House should it transpire.
Based on what?

What makes you think they would go to McCain?

No they are not. Each party selects its slate of electors, and if the majority of the people in the state vote for their candidate then that't the slate that casts their voted in the Electoral College. They are very much partiasan selections.
